The Nithyakalyani Plant (Sadabahar / Saadafuli): A Simple Flower with Remarkable Healing Powers

You’ve probably seen this modest little flower growing along roadsides, in gardens, or in a neighborhood nursery. Known for blooming continuously throughout the year, the Nithyakalyani plant is more than just a decorative shrub. It’s called Sadabahar in Hindi, Saadafuli (सदाफुली) in Marathi, and Nithyakalyani in Tamil. In English, it is widely known as the Madagascar Periwinkle, and its botanical name is Catharanthus roseus.

The name “Saadafuli” and “Sadabahar” both reflect the plant’s constant flowering nature—saada meaning “always” and fuli meaning “flower” in Marathi. It grows all year long, offering daily blooms in vibrant pink and soothing white.

This simple plant, native originally to Madagascar, is now a lifesaving botanical in the world of modern medicine.
Why Is This Plant So Important?

Periwinkle plants from both Catharanthus and Vinca genera belong to the dogbane family. However, among all periwinkle varieties, Madagascar periwinkle (Saadafuli) holds the greatest medicinal value. While people once used it for minor ailments, modern research has shown that it contains compounds that help in fighting serious diseases like leukemia, especially in children.

Traditional and Medicinal Uses of Saadafuli (Sadabahar / Nithyakalyani)

Long before it caught the attention of scientists, this plant was being used in traditional Indian remedies for generations. From treating diabetes to relieving muscle aches, it was an integral part of village medicine.

1. A Natural Ally in Cancer Treatment

An unexpected discovery by two Canadian scientists revealed the anticancer properties of this plant. While testing its use in diabetic treatments, they found that extracts of Saadafuli killed lab cell cultures. This led to the identification of two powerful alkaloids: vincristine and vinblastine.

These compounds were later used to create chemotherapy drugs, especially for conditions like Hodgkin’s disease and leukemia. Today, this unassuming flower saves thousands of lives, making it a precious plant in modern pharmacology.

2. Relief from Wasp Stings

In many Indian households, Saadafuli leaves are used to treat insect stings, especially those from wasps. A paste made from fresh leaves can be directly applied to the sting site, then tied with a clean cloth. It reduces pain and swelling naturally without side effects.

3. Managing Diabetes Naturally

This plant has long been used as a remedy for diabetes, particularly in Indian and Filipino folk medicine. Scientific studies using diabetic rabbits confirmed that Saadafuli helps in reducing blood sugar levels, similar to conventional medications.

People traditionally prepare a tea using dried leaves:

Dry the leaves thoroughly in sunlight.
Grind them into powder.
Boil 200 ml of water and add a pinch of this powder.
Let it simmer and then strain before drinking.
This tea is also used as a gargle for sore throats. 

However, due to the plant’s strong alkaloid content, it should never be consumed in large amounts. Those already taking diabetes medication or pregnant/breastfeeding women should avoid it unless advised by a doctor.

4. Healing Wounds and Cuts

Saadafuli is also used to help heal open wounds and stop bleeding. A decoction made by boiling the leaves in water can be used with a sterilized cloth, applied directly to the wound as a bandage. This method is safe for regular use and helps speed up healing. You can also make a healing oil by simmering crushed leaves in unrefined oil—an excellent home remedy for cuts and scrapes.
Powerful Compounds Behind Its Effectiveness

The healing power of this plant lies in its natural alkaloids, particularly vincristine and vinblastine, found mainly in the leaves and stems. These compounds have strong effects on the body and are responsible for its therapeutic success in treating both minor and serious illnesses.

Safety First: Be Cautious with Internal Use

While applying Saadafuli externally is generally safe, consuming it internally requires caution. Because of its toxicity at higher doses, self-medication can be dangerous. Always consult a qualified healthcare provider before using the plant internally, especially for chronic conditions like diabetes or cancer.
